I tested your city and it loaded for me. Could you please try the following?

To fix this you would need to delete the Local Saved Data File
1) Click on the organizer button in any folder. And select Folder and Search options. Go to view, and under Hidden Files and Folders, or Drives - click show hidden files.
2) Now navigate to C:/users/YOUR USERNAME/AppData/local/DoF/
3) In that file, locate and delete file called local_saved_data
And also make sure of the following:
Right click on Dawn of Fantasy name in your library, and select Properties
Switch to Updates tab, and select - Always keep this game up to date
If it still doesn`t work turn Steam completely off and restart

Let us know if you are still having problems.
